How to SOLDER Sheet Metal

basics of how to solder using muriatic acid, cFLUX, map gas, and tri-bar solder.

[@markizzo3919]

We need more old cats to do vids like this. Thank you for making this and your process was perfect. You could understand how to flow solder a little better but that comes with time and that why I wish more retired people would make videos.

[@sheetmetalstud8740]

Thank you mark

Makes sense that you would be using gas working outside on roofs. As a professional, who has to do this for profit, I am certain that your method is the most efficient and cost effective. My dad started out in the sheet metal trade and he told me that they soldered using soldering irons "coppers" that were heated in a flame. Seems like a lot of steps compared to just using a torch like you do. I am not a professional but do a lot of fabrications at home for different projects where I solder galvanized sheet metal. I use "killed" muriatic only and no flux and an electric soldering iron. I start by wiping the joint with acetone to remove any oils. Next, I wipe the joint with "killed" muriatic acid (ruby fluid), then I "tin" the surfaces that will be in contact by "Wetting" them with solder, then quickly wiping off the excess with a clean dry rag. With the wetted surfaces in contact, I press the iron down over the joint and begin dragging it as I feed in solder. The solder capillaries in as I move along. The result is a clean string joint with no warpage or blobs of solder. I am not criticizing you method; just sharing another way that works.

[@scruffy4647]

What size soldering iron do you use?

[@sheetmetalstud8740]

I like the sounds of that !

[@biglakejudy]

Im a 75 year old woman. Not stupid by any means, can do just about anything I put my mind to. Not only are you too far away for us to see how that bead is being laid down, you put a piece of big metal in the way. You never show the work close up. You should have had a real close shot as you did it. I have no idea what its supposed to look like or how it should act. For Petes Sake...get a grip and figure it out before you waste peoples time. Snort.

[@sheetmetalstud8740]

Judy thanks for snorting, that was friendly

[@Tome4kkkk]

Good demo. Evon though it's not my caliber (I only need some spot soldering sheet metal for model work) it was a pleasure to watch.

Just place the camera to point where you are soldering

[@Breakit_fixit_loseit]

He probably didn’t want to have to camera/tripod right up in his “space”. I can tell you that when I am doing something along these lines; not only do you not want to have anything in your personal space, you want to be able to KNOW you have freedom of movement. You know you can take a quick step back out to the side without hitting your camera/tripod like a line backer.

[@sheetmetalstud8740]

You’re totally correct, i solder everyday but I need to get better with my filming tech

[@gabrielbehrend7625]

You seems like a friendly guy, thanks for putting up a cool video. I’d love to see some window flashing soldered or brazed, maybe you could show a few trick flashing details you have to produce most often in your line of work. Thanks again

This is very helpful! I have to try and solder a galvanized watering can spout back on and it won't stick! Is it just because I need to sand it and add the acid? Or do I need a special kind of solder (tri-bar)? In either case, thanks for the very informative video! I'm going to thumbs up and subscribe to help your channel!

I have a ‘37 Indian junior scout tank that has dents all over it. I believe the inner tank side was silver soldered from the factory. So I melted it all out and removed it so I can planish all the dents out then solder it back in. Kinda nervous cuz it’s not an application at all like this. It’s actually a flange all the way around the perimeter of the tank.

[@xslabcabxhearsex]

That’s one way to do it and it does work.many ways to get the job done. Been doing sheet metal for 31 years.when I solder I use a soldering iron and 50/50 lead bar.use the acid as mentioned and you don’t need flux.with the iron you use a lot less solder and to me have more control of it and is super smooth when done correct

[@Tucko1]

Exactly!! I use a nice clean iron, and suck the solder directly into the seam. Sweat soldered proper.

[@holdenbreau7187]

What kind of soldering iron do you use?

[@PaulHVAC1]

X2 Always a iron & Muriatic Don't need flux..

[@rockman49er]

Did you watch this before you uploaded 👀

[@NorsemenWhite]

Yeah, I’ve been in the trade for over 40 years. I use Morag acid with no flux never seen a problem with it. The one thing I would do is in a bonded situation as I would prime the scenes after you done soldering since you the bond finish off the galvanized finish off to the Ross steel, clean it up wipe it down and prime the scene so no rust occurs. Would you agree or not?

[@illerhag]

Did anyone find a product like the tribar in Europe? I can not find a 50/50 tribar with nickel and tin. Only tin and lead. And lead is not so healthy.

[@rocknfan100]

Very informative ! I'm gonna try it .

[@sheetmetalstud8740]

Thank you Gary and good luck. Soldering is something you just have to do and practice. When you watch someone do it and attempt it personally, it's a whole other ball game

[@rocknfan100]

@@sheetmetalstud8740 Thanks Man. I have a thick copper mini-tub ( oval about 18" X 8" ) and I wanted to use it to ice-down six-pack cans of adult beverages this summer. I got it for cheap $7 @ a yard sale but it leaked around the seam. I scrubbed it out with salt & vinegar and wanted to seal it. I found your video and gave it a shot ( I heated up the seam with MAP first to force out the vinegar and then hit the joint with steel wool). I had all your ingredients already in the garage so I followed your advise. It worked like a charm ! I used the MAP gas on the bottom of the seam and soldered all the way around inside. A quick steel wool scrub and No Leaks. P.S. I remember looking up my grandpa in the 1940 census and his listed occupation was ' Solderer '.

[@toemblem]

I don't know man. It's been a minute since I've soldered sheet metal but this doesn't look right to me. I used an iron and heated the metal and the solder flowed in an easy straight bead.

True MAPP gas production ended in April 2008. What you have is propane gas in a MAPP labeled bottle. They kept the MAPP name as it allowed them to sell more propane. 🤦🏻‍♂️

Potential for a good video but instead you get a Thumbs Down. You can't really see what you are doing and then you go add a big heavy weight weight to hide the view even more. Next time show a close up the process, instead of distant shot from behind you. Also less bragging of your abilities.

I'm tackling a DIY project using 8 ft. corrugated galvanized steel (31-gauge) panels. I need to solder the seams together and have everything ready except the right flux and soldering bars.

If anyone here is looking for a tutorial on how to solder sheet metal....this is not for you, not sure what this other than a "hey look how good I am" video.

do you mind if i ask an odd question. For purpose of thermal exchange (and cost) can you solder a copper heatsink surface to an aluminium water block?

What ratio of tribar solder are you using? You said that it was a nickel mix, but I didn’t find any online when I was looking for that…

[@TheMoonlightCraftsman]

What types of solder work on zinc? I think I have a tin/antimony solder

[@therespectedlex9794]

Is it strong because it's a nickel mix? I want to solder lots of bed springs to make sculptures, maybe.

[@mdalibmaris5175]

You should zoom at the soldering point.....hard to see clearly how the soldering point looks as the soldering work progress.

[@siboolofficial]

Hey, can you please give me an estimate about how much Degrees C is needed to melt your solder? I am planning to use this method for my upcoming project. Thanks.

[@sheetmetalstud8740]

Map gas temperatures are approximately 2,000° C in my torch. You could do it with propane but takes much longer to get to temperature. Once you are skilled, Map gas is the only way to go

[@johnmalan6802]

Great info. I always assumed you had to weld steel sheet. When you end with a funky bead can you go back and grind it down? Does this hurt the strength? Thanks john

I need to solder some 30ga roofing steel to some 5/64 steel bar. I need to put one on each side of a long piece of roofing steel. WHat I'd thought of doing was tinning both the bar and the steel then piling more solder on the bar and melting in on then pressing the sheet down and heating the back of where the solder is.

[@maniacalmonster2293]

Bro. Gloves. Were you melting the solder directly? It looked like you weren’t leading with the flame.

Yes definitely leading with the flame, the solder is always following the heat, I need to do a better job capturing it in a video. Thx for stopping in Irish Monster

[@kylereichstein7578]

Hey man. Hopefully this reaches you in time. I’ve been trying to double lock a sheet metal one into a flat panel for a Standing Seam detail. Unfortunately the metal we are working with is a G90 and not easily as malleable as softer steels do the sheet keeps tearing. I ran into your video while looking for ways to solder the cone to the panel. My question is, what and where do you get this acid? Is it absolutely necessary? I’d like to make sure this solder does not break. Where can I find the flux? Thanks and hopefully this reaches you before I have to do this on a wimb 😂

[@zackpoll8893]

Muriatic acid is at Lowe’s and HD.

[@randy1ization]

dont ever let even a drop of water fall into that acid, it will explode!

[@jorgecallico9177]

Helpful. Years ago I used C-Flux on copper but later found it too corrosive. It's nice to learn that it's original intent is for steel.

[@mgoswick9250]

Yea doesn’t flux follow the heat. So you’d start @ bottom right. Or els the solder will run down on none heated area & cause a ugly mess.

Is that galvanized sheet metal?

[@sheetmetalstud8740]

what I was soldering in that shot wasa funky looking piece of bonderized metal. It was so scratched up we just ground it down so it looks shiny like galvanized, its a cleaner look if we need to use it in the future. I just randomly grabbed that to solder and it actually was moving on me at the seam I was soldering and I having trouble. I decided to keep it in the video because life isn't perfect. Often I lay a real nice bead of solder but on that one it wasn't very pretty. Thanks for asking questions! If there is anything else I can answer or help with please let me know. Have a great day.

Trained professionals don't solder sheet metal with an open flame on a roof deck. Just about every part of what this video purports to demonstrate is incorrect, from the torch to the fluxes to the solder to the finished product. Get some professional training, or at least do a modicum of research on how to properly solder sheet metal. This is not how to go about it
